Xueba, I beg you to go and escort him quickly!

Although Zhou Luzhe's house is close to 200 square meters, this includes the shared area!

Excluding the public stall, it is much smaller!

With 4 more rooms separated, the living room is even smaller.

Xu Heng sat on the sofa and turned on the TV.

But still couldn't hide the surprise in the room.

"What! What did you say?!"

"real or fake!"

"What you said is true! Xu Heng really...!"

"My God! It's real!"

"Is Xu Heng so powerful now?"

"Xu Heng, he..."

"..."

All kinds of shock!

All kinds of surprises!

Each link is repeatedly emphasized!

Geng Xiaoyan is 1 do not believe it!

It was obvious that they had watched Xu Heng grow up, and they knew best what Xu Heng was like.

But today, what Zhou Luzhe said, Geng Xiaoyan couldn't agree with Xu Heng!

"This, this, this should be someone else's child!"

"How could it be that Xu Heng who sneaked up on chickens and dogs, climbed trees and went down rivers when he was a child!"

"I'm messed up!"

"Pinch me! I'm not dreaming, am I?"

"Ah! It hurts...you are too hard, it's annoying."

"..."

Xu Heng outside is not well.

You talk about things, just talk about things, why are you showing affection!

And at this time, Zhou Xiaoya came out.

Wearing a skirt that fits well, the whole person looks fairy-like.

"Brother! What do you think?"

Xu Heng gave a thumbs up, "It looks good!"

Zhou Xiaoya, "Okay! Then I'll change it! I'll wear it in summer! You go to the study and wait for me! I have a lot of questions to ask you, bro!"

Zhou Xiaoya loves to study and likes to study.

Her grades have declined, not because she doesn't study hard, or because she doesn't want to study, but because her grades have been very unsatisfactory.

Do more with less!

Xu Heng went directly to the study, ignoring Zhou Luzhe and Ge Xiaoyan.

After Zhou Xiaoya changed her clothes, she came to the study.

He just sat down and handed the monthly test paper to Xu Heng.

"Brother! I haven't finished my math this time...I feel like I did badly in the exam..."

Xu Heng probably looked at the test paper.

Zhou Xiaoya was on the side, blinking her big eyes, and asked in a low voice, "Brother! Do you want to read these questions first? How long will it take?"

What Zhou Xiaoya meant was whether Xu Heng should do it by himself first, after all, to explain the test paper to himself, he needs to understand everything first, and the plenary session.

It will take some time!

But after Xu Heng browsed around, he asked, "You don't know the questions marked in red here, do you?"

Zhou Xiaoya nodded obediently.

Xu Heng, "Okay! Then let's do one question at a time, slowly trying to help you straighten out this set of math test papers, and then pass these questions to popularize relevant knowledge points for you!"

Zhou Xiaoya looked at Xu Heng, slightly stunned.

"Brother! I feel that you have changed...you are not like you before..."

Xu Heng rolled his eyes at Zhou Xiaoya, "How do you say?"

Zhou Xiaoya murmured, "You've become handsome! You're as handsome as the hero of the show I'm chasing! No! You're even more handsome than the hero!"

Xu Heng, "%￥##￥￥..."

"Stop talking, hurry up! Look at the question."

Zhou Xiaoya came back to her senses, and was really shocked in the next second, "Brother! You, you just read the question once, and you know the answer? Do you know how to explain the question to me?"

Xu Heng shrugged, "Otherwise?"

Zhou Xiaoya pouted.

Xu Heng, "You're just a test paper for the third grade of junior high school, so it's hard to stop me?"

Zhou Xiaoya "???"

"But... my classmate's sister who is in college, seeing this set of test papers, finds it difficult..."

Xu Heng, "Then his sister must be a scumbag?"

"Here's a copy! The mathematics department...how could it be a scumbag."

"It is said that it takes a long time to do this set of questions, bro... can you do it?"

Xu Heng rolled his eyes at Zhou Xiaoya again.

Zhou Xiaoya continued to curl her lips.

Xu Heng, "Let's read the questions!"

topic:

求根号下（2-4根号下（3-2根号下2））

Xu Heng, "In this question, there is a root number under the root number, and under the root number, there are also root numbers, triple root numbers."

"No matter how complicated it is, the method is still very simple."

Simple……

???

Zhou Xiaoya was extremely helpless, it was so simple, she had a headache when she saw it.

Xu Heng had already taken the pen and paper, and was just about to continue.

"Dong dong dong..."

Zhou Luzhe pushed the door open and came in, "Well...Xu Heng, let me ask you about the previous tax situation, I want to ask..."

Xu Heng probably talked to Zhou Luzhe.

Zhou Luzhe, "Okay, okay, I understand, you guys go on, go on!"

But within a few seconds, Zhou Luzhe came back and asked Xu Heng a lot of questions.

Zhou Xiaoya tilted her head, speechless, "%￥##@#￥......"

"Dad, you are too much! You obviously asked my brother to tutor me! What do you keep asking?"

"Get out! Get out! Don't come in! I cut in the door!"

Click!

Really lock the door!

"Don't knock on the door!"

"Brother! You continue!"

PS: Thank you [Ying Xuanyi] for your support!Kneel for all support! .

Chapter 316

"Brother! You go on! You go on!"

"No one bothered us this time!"

Zhou Xiaoya was sitting next to Xu Heng, and she looked forward to it.

Xu Heng held the live broadcast, talking and writing at the same time.

"This question uses the perfect square."

"From inside to outside, come one by one."

“先看里面的3-2根号下2,3可以分成什么？是不是2和1？”

Zhou Xiaoya blinked her big eyes, "Mmmmmmm!"

Xu Heng took advantage of the situation and wrote:

3-2根号2=2-2根号2+1=（根号2）2-2根号2*1+12=（封号2-1）~2

"So, got it?"

Zhou Xiaoya's eyes widened, "Understood! I understand! I have been misled by my thinking before-!"

"Brother! What you said is different from what the teacher said!"

Xu Heng hit the nail on the head, "Sometimes what the junior high school teachers say is to take care of most of the students. There are more things that you need to understand yourself, and you have to have your own set of learning methods."

"So, this question, you can complete it yourself."

Following Xu Heng's steps, Zhou Xiaoya followed suit and quickly gave the answer.

"Brother! The answer is 2-root 2, right?"

Xu Heng nodded.

"yeah!"

Zhou Xiaoya was excited.

Xu Heng, "You girl is too happy."

Zhou Xiaoya, "???"

Xu Heng, "I've summed it up. I think it's necessary for me to talk about some graph theorems with you about the types of questions you have drawn."

Zhou Xiaoya?

Xu Heng came right away, "Let's talk about Vivinia's theorem first."

Zhou Xiaoya, "???"

"Are you sure there is such a theorem?"

Xu Heng drew an equilateral triangle on paper.

"To make a height, the sum of the distances from any point of the triangle to the three sides is equal to the height."

"It's so simple, you just need to remember it!"

"Let's look at another one, Archimedes midpoint theorem."

Xu Heng drew a circle casually.

"Draw two chords on the circle, one big and one small... Pay attention to the picture and see the A, B, C, 0, P, and D I marked."
